1990 Wrangler with AX15 transmission. The transmission had a mild grind that could be felt mildly during shift. Grind into reverse almost every time. It's currently at a reputable transmission shop and they are running out of ideas. The pedal engages close to the floor. They have replaced the master 3x now and it just doesn't seem to want to pressurize. The clutch, slave and pilot were also replaced. They just went into the internals today and said everything looked great inside with the exception that the shifter bushing needed replacing. Any ideas on how to get the master up to pressure?
